FAS TENING FOR DOORS AND WINDOWS.

SPECIFICATION formingpart of Letters Patent No. 228,698, dated June 8, 1880.

Application filed May 7, 1879.

To all whom it may concern Be it known that I, NATHAN THoMPsoN, of Brooklyn, in the county of Kings and State of New York, in the United States of Amer ica, but at present of 23 Southampton Buildings, in the county of Middlesex, England, have invented new and useful Improvements in Means for Locking or Fastening Doors and Windows, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings.

My invention consists, primarily, in the employment of peculiarly constructed and arranged curved rotating wedges, in combination with staples, hasps, loops, slotted bolts or pins, or suitable bars, studs, or projections for looking or fastening doors and windows. These curved wedges have their outer parts formed in the shape of part of a circle, or approximating thereto, and in forcing them into position they are caused to travel in a circular path struck from a point in the center of such curved wedges. These curved wedges may be used as separate articles, in which case their thicker ends are so formed or extended as to enable a spanner or lever to be applied thereto, or they may be mounted on an axis supported in a suitable hearing or bearings carried by a plate and operated by a lever fixed thereto or capable of being applied thereto when desired. When mounted on a shaft or axis two of such curved wedges may be formed or fixed on the same shaft or axis at opposite ends thereof, in order that two sides or parts of a door, window, or other article may be locked, fastened, or connected together by a single operation.

In some cases the plate or plates carrying the shaft or axis of the curved wedge or wedges projects or project beyond the edge of the article to which it is fixed, and the hasp, loop, staple, bar, stud, or projection, acting in combination with each curved wedge, passes through a slotted opening in the plate, in which case, in order to admit of slight variation in position of the parts, the sides of the slotted openings are beveled, and the hasps, loops, staples, bars, studs, or projections may be somewhat lengthened, while one or both sides of the nose of the curved wedge may be also beveled for the same purpose. The

curved wedge passes through the hasp, loop, staple, slotted bar, or bolt, or the inclined surface thereof acts against a suitable bar, stud, or projection, and thereby forces the two parts firmly together.

I also form the curved wedge, at the inner end of the inclined portion thereof, with a concentric part, which serves to secure it in its locked position, and in some cases I somewhat extend the nose of the curved wedge, or reduce it on the back, to facilitate its application, and I sometimes apply a spring, or a catch or bolt. to hold it in its locked or unlocked position.

In order that my invention may be more clearly understoood and readily carried into effect, I will proceed, aided by the accompanying drawings, more fully to describe the same.

Figure 1 is a front View. Fig. is a sectional edge View; and Fig. 3 is a sectional plan, representing my improved lock or fastener applied to a door. Fig. 4 is a sectional edge view of the same, showing the door not quite closed, and the circular wedge with its nose just about to enter the hasp or loop on the door-post. Fig. 5 is a front view, and Fig. 6 is an edge view, of part of a door with myimproved lock or fastener applied thereto; and Fig. 7 is a front view, and Fig. 8 is a sec tional plan, of part of a door-post with the hasp or loop fixed in position thereon. Fig. 9 is similar to Fig. 8, except that the opening in the hasp or loop is narrower in Fig. 9 than that shown in Fig. 8, to enable my improved lock or fastener to draw the door close up to the door-post; and Fig. 10 is a side view, drawn to a larger scale, of one of my improved fasteners.

In all the figures like parts are marked with similar letters of reference. 7

My fastener consists of a curved rotating wedge, formed on its outer part in the shape of a part of a circle, or approximating thereto, and inclined in the directionof the curve, so that in forcing the fastener into position it will travel in a circular path around a point in the center of such circular wedge, draw the two parts to be fastened firmly together, and lock them accurately in position. These curved rotating wedges are also formed at the innerv end of the inclined portion thereof with a concentric part, [0 which serves to secure them in their locked position; and in some cases I somewhat extend the nose a of the curved wedge, or reduce it on the back, as shown by dotted lines in Fig. 10, to facilitate its application, and as represented at Figs. 1, 5, and 6. In some cases these curved rotatingwedges are used as separate articles, in which case their thicker ends a are so formed or extended as to enable a spanner or lever to be applied thereto. These curved rotating wedges a are mounted on an axis, 70, supported in a bearing, 1, (or it may be bearin gs carried by a plate, 1,) and are operated by a lever, a fixed thereto, or capable of being applied thereto when desired,and, if desired, two of such curved rotating wedges a may be formed or fixed on the same shaft or axis 70 at opposite ends thereof, such shaft or axis 70 being suitably lengthened and mounted for the purpose, in order that two sides or parts of a door or window inay'be locked, fastened, or connected together by a single operation.

The plate Z, carrying the shaft or axis 70 of the curved rotating wedge to, projects beyond the edge of the door m, to which it is fixed, and the hasp, loop, or staple cl, acting in combination with such curved wedge a, passes through a slotted opening, I, in the plate l; and in order to admit of slight variation in position of the parts, and yet secure their proper relative adjustment with each other, the sides I of the slotted opening Z are beveled, and the hasp, loop, or staple d may be somewhat lengthened, as represented at Fig. 8, while one or both sides of the nose (0? of the curved wedge a may be also beveled for the same purpose, as shown.

The hasp, loop, or staple d is carried by a plate, 61, fixed to the door-post n.

In some cases a spring or a catch or bolt may be employed, in connection with the curved rotating wedge, to hold the latter in its locked or unlocked position, as will be well understood.

In the drawings I have shown my invention as applied to the fastening of doors and windows only; but it is equally well adapted for securing the heads of cylinders or the covers thereof, and for securing furniture and various other articles where two or more parts or pieces are clamped or drawn together in order to lock them.

Having thus described the nature of my said invention, and the mode in which I carry the same into effect, I would have it understood that what I claim is- 1. The combination of plate Z, slotted at its outer edge to receive a hasp or staple, staple d, and curved rotating wedge a, as and for the purpose set forth.

2. The plate Z, arranged to project beyond the edge of the door or window, and having the slotted and beveled portion 1 Z bearing or standard Z, axis k, and curved rotating wedge a, substantially as set forth.
